LEVI O. KENTON, OF BALTIMORE, MARYLAND, ASSIGNOR OF ONE-HALF TO JAMES CLEMENT, OF SAME PLACE.

SHOE- SOLE-EDGE SETTER.

SPECIFICATION forming part of Letters Patent No. 375,074, dated December 20, 1887.

Application filed September 29, 1887. Serial No. 251,001. (No model.)

To all whom it mciy concern.

Be it known that I, LEVI O. KENTON, a citizen of the United States, residing at Baltimore, in the, State of Maryland, have invented certain new and useful Improvements in Shoe- Sole-Edge Setters, of which the following is a specification.

My invention relates to a machine for setting the edges of shoesoles and bnrnishing the same.

The invention is illustrated in the accompanying drawings, in whicl1- Figure 1 is a side elevation of the machine. Fig. 2 is a top plan of same. Fig. 3 is a vertical crosssection on the line 3 3. Fig. 4 is a cross-section on line 4. Fig. 5 is a cross-section on line 5. Fig. 6 is a side view of the lower crank-shaft. Fig. 7 is a front viewof Fig. 8 is a view Fig. 9 is a sectional view of the crank-collar.

Fig. 10 is a front view of of the tool-holder. the tool-holder.

The letter A designates the stand, supported on legs a. A driven shaft, 1), is below the stand,and is supported by bearings b. A drivepulley, c, and a loose pulley, c, are on this shaft, and at each end is a crank-head, d, to which is attached an upward-projecting rod, e. Above the stand are two oscillating shafts, F, each independent of the other, and both supported in bearings g g,and having position end to end and in line with each other. The object of having two separate shafts F is to enable two operators to work at the machine and not interfere with each other. The ends of both shafts F occupy the same central bearing, g, and there is space sufficient in said bearing between the ends for a separating block, h.

Each shaft F has a collar, 0, which is .connected by a groove, z, and feather i, (see Figs. 2 and 4,) so as to permit the collar to move lengthwise, but not to turn on the Shaft. A spiral spring, j, surrounds each shaft between the said collar and the central bearing, 9, and serves to keep the collars pressed in one direction. The collar 0 has near one end an annular or circumferential groove, is, and a le ver, L, has one end pivoted at Z to the standtop, and has an upward-projecting lug, 7a,

which takes into the said groove k. The free end of the lever has a knob, Z, to be grasped by the hand. By moving this free end of the lever toward the central bearing, 9, the spiral springj will be compressed and the one collar 0 moved lengthwise on the shaft toward the central bearing, 9. The collar 0 has at one end two lugs, m, which project in line with the shaft. A crank-collar, N, is loose on the shaft F, and may be oscillated thereon freely. It has a crank-arm, n, which is longer than the throw of the wrist d on the crank-head (I, and the rod leading from the said crank-head on the lower shaft connects with the arm a on the crank-collar N.

The crank-collar is provided on its end with two notches, m, to receive the lugs m on the sliding collar. When the spiral spring j presses the collar 0 endwise, the lugs in will enter the notches m, thereby connecting the loose crank-collar N rigidly with the oscillating shaft F, and thereupon the revolving motion of the drive-shaft b will impart an oscillating motion to the shaft F.

From this description it will be seen that two independent oscillating shafts, F, are connected with one driveshaft, b. Vhile the machine is thus constructed double, it may be made and used single-that is, with only one shaft F. At the end of each oscillating shaft F is a head or tool-holder, I, which is reversible on the said shaft. This holder carries two burnishing-tools, 0 and 1), one of which is set diametrically opposite the other. The tool (either 0 or which may be sitting lowermost or pointing downward is the one in position for use. This lowermost tool is in position to receive the jet-flame q from a gaspipe, q, and the toolis thereby heated. A suitable handsupport, 1', is fixed to the stand. The one to the right of Fig. 1 consists of a disk, r, having a central pivot, r. The back of the operators hand,which may be grasping the shoe, is placed against this pivoted disk. The one to the left of Fig. 1 consists of a hook, a".

The tool-holder I is centrally pivoted at the set.

two holes a in the holder I and retains the latter at either position to which it may be The object of having two tools, 0 p, on the one holderand making the said holder reversible is to use two tools, each having a burnishing-face of different designone tool suited for setting the edge of the sole around the broad part of the tread and toe, and the other tool for setting the edge of the sole at the shank or bottom hollow of the sole.

Both tools 0 and p are detachable from the holder by loosening the set-screw o. The burnishing-tools 019 have a vibrating motion in a vertical plane, produced by the oscillation of the shaft 12. This vibration may be regulated so as be longer or shorter.

The cranlchead d is provided with an adjustable wrist, d, to which the rod 6 is attached. This wrist d is attached to a plate, w, which has slots 00, and occupies a diametrical groove, 10, on the crank-head. Each slot in the wrist-plate w is occupied by a set-screw, y, on the crank-head, and thereby the wristplate may be adjusted so as to locate the wrist d at any desired distance from the center of the crank-head, and thus shorten or lengthen the vibration of the burnishing-tool.

The lever L carries ahook, z, provided with a downward prong, e, which engages with a hole, 2 in the stand-top. Vhen the lever L is moved to withdraw the collar 0 from engagement with the crank-collar N, this hookz will retain the lever to the moved position and prevent the spring from forcing it back.

The operation will be readily understood from the foregoing description. Thelower tool, which does the work on the edge of a shoesole, has a rapid vibrating motion, which is peculiarly well suited to produce good results on the leather.

Having described my invention, I claim and gesire to secure by Letters Patent of the United tates- 1. A shoe burnishing machine having, in

combination, a driven shaft, 12, provided with two crank-heads, d, two oscillating shafts, F, both provided with a crank-arm, n, and a burnishing-tool, each independent of the other, and a rod, 6, connecting each of the said crankheads with one of the crank-arms. 2. A shoe-burnishing machine having, in combination, adriven shaft, b, provided with a cranlchead having an adjustable wrist, d, an oscillating shaft, F, having a crank-arm, n, and provided with a tool-holder and tool, and a rod, e, connecting the adjustable wrist and crank-arm.

3. A shoe burnishing machine having, in combination, a driven shaft, 1), provided with a crank -head, an oscillating shaft provided with a collar, 0, having lugs m, and so connected with the shaft as to move lengthwise, but not turn, a spring, j, pressing against said collar, a crank-collar, N, having an arm, a, and notches m, and mounted loose on the oscillating shaft, and a rod, 6, connecting the said crank head with the arm of the crankcollar.

4. A shoe burnishing machine having, in combination, a driven shaft, b, provided at each end with a cranlchead, d, two oscillating shafts, F, both provided with burnishing-tools, and each having position end to end and in line with each other, two cranlccollars, N, each having an arm, n, and each mounted on a different one of the oscillating shafts, a clutchcollar, 0, on each shaft, and rods e, connecting the crank-heads with the arms of the crankcollars.

In testimony whereof I affix my signature in the presence'of two witnesses. V

LEVI O. KENTON.
